[Roentgenography of the skin and subcutaneous tissue in postmastectomy edema of the upper extremities].

The results of radiography of the forearm and shoulder soft tissues in 47 patients with postmastectomy syndrome before and after conservative treatment and in 6 controls made it possible to determine differences in x-ray imaging of a skin and subcutaneous fat layer in limb edema. These differences were determined by lymph flow disorders and the formation of a connective tissue component in subcutaneous fat and could be used for objective assessment of a degree of edema, determination of tactics of rehabilitation activities and assessment of their effectiveness.

[Automated roentgenography of the thoracic organs].

A new device is developed to trigger automatically an X-ray unit at the instant of the extremum respiratory phase. The device is driven by a probe sensing the air stream. The serviceability of the unit has been tested in the course of pneumopolyradiographic and pneumotetraradiographic examinations in more than 5000 patients. The unit is recommended for clinical application in the X-ray departments.

[Anatomically shaped, unsharp, lead-containing acrylic glass filter for optimization of thoracic roentgenography].

Acrylic glass filters fitted near to the tube and shaped according to the patient's anatomy with a lead equivalent of 120 mu enhance the diagnostic value of a plain radiograph of the chest with 95% of the patients. The pulmonary vessels and mediastinal structures can be assessed on film. Compared with the X-ray film without filter, the pulmonary vessels are visualised with equal clarity. Accurate adjustment of the patient is facilitated by the fact that the filter limits show up in the light viewfinder. Repeat X-ray films are necessary in less than 2% of the case. Artifacts are caused by anatomical chest variations as well as by large patients, and hence the use of the filter should be omitted in about 5% of the patients.
